Adaptive Power Control Command Transmission Rate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, the power-control process often fails to align the actual and expected transmission power adjustments of access terminals with the access network, leading to suboptimal communication quality and increased interference due to missed power control commands.
Innovation Solution
The power-controlling entity monitors the actual and expected transmission power adjustments and adjusts the power control command transmission scheme by altering the transmission rate or power adjustment values to ensure closer alignment, thereby improving synchronization and reducing network resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power-controlling entity sends power control commands at a standard transmission rate, then the system operates with predefined protocol compliance, but the actual and expected transmission power adjustments fail to align due to missed commands
Solution Approach 1:
The patent applies dynamics by making the power control command transmission rate adjustable rather than fixed. The power-controlling entity dynamically alters the transmission rate based on monitored alignment between actual and expected power adjustments, transitioning from a static protocol-defined rate to an adaptive rate that responds to channel conditions and command reception status
Solution Approach 2:
The patent changes the transmission rate parameter of power control commands from a fixed standard value to a variable parameter. The system monitors alignment metrics and adjusts the transmission rate parameter accordingly, allowing the same system to operate at different rates depending on observed performance and alignment requirements
2Reliability
If the transmission rate of power control commands is increased, then the receipt rate of commands improves and alignment enhances, but the system complexity and protocol deviation increase
Solution Approach 1:
The patent implements feedback by having the power-controlling entity monitor the alignment between actual and expected transmission power adjustments, then using this monitoring information to adjust the transmission rate. This closed-loop feedback mechanism allows the system to automatically optimize command delivery without manual intervention or complex external control
Solution Approach 2:
The system performs self-service by autonomously adjusting its own transmission rate based on internal monitoring of power adjustment alignment. The power-controlling entity uses its own observed performance metrics to modify its transmission behavior, eliminating the need for external system modifications or additional complex coordination mechanisms
3Reliability
If the power control command transmission scheme is altered to improve alignment, then communication quality improves, but network resource consumption increases
Solution Approach 1:
The system dynamically adjusts the transmission rate based on observed alignment needs rather than operating at a constantly high rate. When alignment is achieved or channel conditions are good, the system can revert to lower transmission rates, consuming fewer network resources while maintaining reliability when needed

AI summary
While a first and second entity are engaging in a communication session on a wireless link, the first entity may be sending a series of power control commands (PCCs) directed to the second entity at a first transmission rate. Additionally, the first entity may monitor an actual and expected transmission-power adjustment of the second entity. Based on this monitored actual and expected transmission-power adjustment, the first entity may decide to alter the PCC transmission scheme for the second entity. For instance, if the monitored actual and expected transmission-power adjustment differs by a threshold extent, the power-controlling entity may decide to increase the PCC transmission rate for the power-controlled entity and/or increase the transmission-power adjustment instructed by PCCs directed to the second entity. In response, the first entity may begin sending the series of PCCs directed to the second entity according to the altered PCC transmission scheme.
